Question Discussion & Solution

​The correct answer is Truck farming.

Key Points

• The farmers specialize in vegetables only, this type of farming is known as Truck farming.
• In the regions where farmers specialize in vegetables only, the farming is known as Truck farming, and the distance of truck farms from the market is governed by the distance that a truck can cover overnight, hence the name truck farming.
• Vegetable farms are in some regions known as truck farms: "truck" is a noun for which its more common meaning overshadows its historically separate use as a term for "vegetables are grown for the market".
• The production of crops of some vegetables on an extensive scale in regions especially suited to their culture primarily for shipment to distant markets known as Truck farming.
• The major truck-farming areas are in California, Texas, Florida, along the Atlantic Coastal Plain, and in the Great Lakes area.
• Centres for specific crops vary with the season. Among the most important truck crops are tomatoes, lettuce, melons, beets, broccoli, celery, radishes, onions, cabbage, and strawberries.

Additional Information

The correct answer is In 1982.

• The National Bank for Agriculture and Rural Development (NABARD) is a top-level development financial institution in India, established in 1982 to provide agricultural and rural credit.

Key Points

• National Bank for Agriculture and Rural Development (NABARD) is the apex institution of Rural Credit.
• It was established on 12 July 1982 by the merger of Agriculture Credit Department and reconstruction of Agriculture and Development Corporation of the Reserve Bank of India.
• Its establishment is based on the recommendations of Shivraman Committee.
• Food stocks are maintained by the Central Government for three purposes:
  • Maintaining prescribed buffer stock norms for food security,
  • Monthly supply through Public Distribution System (PDS),
  • Market intervention to stabilise open market prices.

The pattern followed is

The pattern followed is:

There are two series here:

i) 5, 10, 20, 40, 80

5 × 2 = 10

10 × 2 = 20

20 × 2 = 40

40 × 2 = 80

ii) S, R, Q, P, O

S - 1 = R

R - 1 = Q

Q - 1 = P

P - 1 = O

Hence, the correct answer is "80O".

The correct answer is Ammeter.

Key Points

• Ammeter
  • An ammeter is an instrument that is used to measure the current in the circuit.
  • It measures either direct or alternating electric current, in amperes (A).
  • It has a set of coils with very low resistance and inductive reactance.
  • This allows for very low impedance, the force that opposes electric current.

Additional Information

• Wattmeter
  • The wattmeter is an instrument for measuring the electric active power in watts of any given circuit.
  • Electromagnetic wattmeters are used for the measurement of utility frequency and audio frequency power; other types are required for radio frequency measurements.
• Hygrometer
  • Hygrometer instrument used in meteorological science to measure the humidity or amount of water vapour in the air.
• Pyrometer
  • A pyrometer is a type of remote-sensing thermometer used to measure the temperature of distant objects
